Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention desorbs moisture from the adsorbent by applying air heated by a heating means to the adsorbent that adsorbs the moisture in the air and contains the desorbed moisture. The present invention relates to a humidifying device that does not need water supply to supply fresh air into a room.

[0002]

2. Description of the Related Art Conventionally, as a humidifier, there is a humidifier disclosed in Japanese Patent Application No. 8-199473 proposed by the present applicant.

FIG. 9 is a main part perspective view showing the humidifying device. In the figure, A is the first air flow and B is the second air flow.

The humidifier 110 is arranged indoors, and has an adsorbent 101, a drive belt 102, and a drive motor 10.
3, a blower device 104, 105, and a heater 106.

The adsorbent 101 adsorbs the moisture in the air flow A when the air flow A introduced from the room by the drive of the air blower 104 passes through the adsorbent 101 and the air blower 10
When the air flow B, which is guided from the room by the drive of No. 5 and heated by the heater 106, passes through, the water adsorbed on the adsorbent 101 is desorbed into the air flow B.

The humidifying device discharges the air flow A to the outside of the room and guides the air flow B into the room so that the humidification can be performed without supplying water.

[0007]

However, in the above-described conventional humidifier 110, in order to improve the humidification efficiency, the air flow rate of the air flow A must be set larger than the air flow rate of the air flow B. In this case, the blower 104 has to be upsized to discharge a large amount of dry air to the outside of the room.

Moreover, if there is a distance between the humidifying device and the outdoor, the pressure loss due to the air blow is large for exhausting the outdoor air, and the air blower must be upsized.

However, in the conventional humidifier 110, since the air blower 104 is installed indoors, the air blower 104 is not provided.
When the size of the fan is increased, the noise and power consumption of the air blower 104 in the room increase.

Further, the conventional humidifier is not provided with an air cleaning means for purifying the air flow B and a deodorizing means for deodorizing the odorous components contained in the air flow B, so that the air in the room is purified and deodorized. Could not be done. Moreover, since the airflow A is discharged to the outside of the room, the same amount of outdoor air as the exhausted indoor air will flow into the room by natural ventilation through the gaps in the room, etc. When the air contains an odorous component, there is a problem that the indoor air becomes dirty or the odorous component flows in.

In view of the above problems, it is an object of the present invention to provide a humidifying device capable of reducing the noise of the blowing means in the room.

BEST MODE FOR CARRYING OUT THE INVENTION A humidifying device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing a humidifying device according to a first embodiment of the present invention, and FIG. 2 is a perspective view of a main part of the humidifying device shown in FIG.

In the figure, 1 is an adsorbent, 2 is a drive belt, 3 is a drive motor, 4 and 5 are blowers, 6 is a heater,
Reference numerals 7 and 8 are air flow passages, and 10 is a humidifying device. Also, A
Is a first air flow, B is a second air flow, 11 is outdoor, 12
Indicates the room.

The adsorbent 1 is in the form of a honeycomb cylinder, and is connected to the drive motor 3 by the drive belt 2. When the drive motor 3 rotates, the adsorbent 1 rotates via the drive belt 2. The adsorbent 1
The shape does not have to be a honeycomb shape as in the present embodiment, and may be a lattice-like shape, a sponge shape, a mesh shape, or the like, which is breathable.

The blowers 4 and 5 are installed in the two air passages 7 and 8, respectively. That is, the air blower 4 is installed in the air flow passage 7, and the air blower 5 is installed in the air flow passage 8.

When the blower 4 is operated, the air outside 11 is taken into the first air flow passage 7, becomes an air flow A and passes through the adsorbent 1, and the air flow A is exhausted to the outside 11. It

When the air blower 5 is operated, the air from the outside 11 is taken into the second air flow passage 8 and becomes the air flow B, which is heated by the heater 6 and then passes through the adsorbent 1 to reach the inside of the room. Sent to 12.

The blowers 4 and 5 do not need to be installed on the downstream side of the adsorbent 1 as in the present embodiment, and the adsorbent 1 is not required.
It is sufficient that the air is blown to the air flow passages 7 and 8 of the two systems, such as being installed upstream of the heater 6 or upstream of the heater 6.

In the humidifying device having the above-described structure, when the blowers 4 and 5 are operated, the outdoor air is humidified by the humidifying device 1.
Inhaled within 0. When the airflow A passes through a part of the adsorbent 1, the moisture in the airflow A is adsorbed by the adsorbent 1 and is exhausted to the outside 31 as dry air. The air flow B is heated by the heater 6 and passes through a part of the adsorbent 1 to heat the adsorbent 1. Since the adsorbent 1 is rotating, the part containing water moves to the air flow passage 8 and is heated to evaporate the water and sent to the room 12 as humidified air.

As described above, according to the humidifying device 10 of the present embodiment, since the air blowers 4 and 5 are arranged outside the room 12, the noise generated by the air blowers 4 and 5 is outdoors. The noise of the blowers 4 and 5 in the room 11 can be reduced as compared with the conventional case where the blowers 4 and 5 are arranged in the room 11.

Further, since the adsorbent 1, the heater 6 and the air flow passage 8 are arranged outside the room 12, and the air blowers 4 and 5 blow outdoor air to the adsorbent 1, the air blower is the same. Compared with the case where the adsorbents 1 and the heater 6 are disposed inside the room 12 and the adsorbents 4 and 5 are disposed outside the room 11, a ventilation passage (air flow passage) that connects the air blowers 4 and 5 and the adsorbent 1 ), It is possible to shorten or eliminate the air passage for guiding the air flows A and B to the adsorbent 1 and the air passage for discharging the air flow A to the outside 11. As a result, the pressure loss due to the ventilation of the ventilation passage can be reduced, the blowers 4 and 5 can be prevented from increasing in size, and along with this, noise can be reduced and energy can be saved.

That is, in the humidifying device 10 according to the present embodiment, the air flow passage 8 for supplying air to the room 12 becomes longer and the intake flow passage 7 for exhausting air to the outside becomes shorter than in the conventional humidifying device. ing. Air flow A flowing in the air flow passage 7
Is a large amount of air flow compared to the air flow B flowing through the air flow passage 8 due to the difference between the adsorbed amount and the desorbed amount with respect to the air flow rate. When the passage 8 is lengthened, it is possible to reduce the pressure loss of the blown air as compared with the case where the air flow passage 7 with a large intake flow rate is lengthened as in the conventional case. Therefore, it is possible to reduce noise in the room 12 and save energy for driving the blowers 4 and 5.

In the present embodiment, it is possible to operate only the air blower 4 (that is, to operate the air blower 4 and stop the drive motor 3, the air blower 5 and the heater 6). When only the blower 4 is operated, the room 1
Air supply to 2 is performed. When the air is supplied, the same amount of the air in the room 12 as the supplied air in the room 12 is exhausted to the exterior 11 by natural ventilation from the gap or the like in the room 11, so that the room 12 can be ventilated.
